2021-12-22Add text wrapping to HTML output.John MacFarlane1-1/+2
Previously the HTML writer was exceptional in not being sensitive to the `--wrap` option. With this change `--wrap` now works for HTML. The default (as with other formats) is automatic wrapping to 72 columns. A new internal module, T.P.Writers.Blaze, exports `layoutMarkup`. This converts a blaze Html structure into a doclayout Doc Text. In addition, we now add a line break between an `img` tag and the associated `figcaption`. Note: Output is never wrapped in `writeHtmlStringForEPUB`. This accords with previous behavior since previously the HTML writer was insensitive to `--wrap` settings. There's no real need to wrap HTML inside a zipped container. Note that the contents of script, textarea, and pre tags are always laid out with the `flush` combinator, so that unwanted spaces won't be introduced if these occur in an indented context in a template. Closes #7764.
2020-07-01HTML writer: improve alt-text/caption handling for HTML5Albert Krewinkel1-1/+1
Screen readers read an image's `alt` attribute and the figure caption, both of which come from the same source in pandoc. The figure caption is hidden from screen readers with the `aria-hidden` attribute. This improves accessibility. For HTML4, where `aria-hidden` is not allowed, pandoc still uses an empty `alt` attribute to avoid duplicate contents. Closes: #6491
